Title: Acceleration integrating type vehicle speedometer
Inventor: OSOKOSHI TOSHIKUNI
IPC: G01P7/00
Filed: 1984-12-21
Abstract: PURPOSE:To enable continuous measurement of the vehicle speed to match actual state, by arranging a feedback circuit to perform a coefficient correction for a multiplier so as to make the deviation zero between a vehicle velocity signal VV and a wheel velocity signal VW determined separately. CONSTITUTION:A comparator 4 determines the deviation between a vehicle velocity signal VV and a wheel velocity signal VW. The deviation thus obtained is inputted into a coefficient correction circuit 5 which performs a coefficient correction for a multiplier so as to make said deviation zero between the VV and VW. A feedback circuit thus arranged is built. Therefore, the coefficient correction for the multiplier is performed only when braking is OFF while a brake switch 6 starts to work and a vehicle velocity signal VV is outputted based on the coefficient fixed at the startup of the braking. With such an arrangement, error factors such as effects from changes in the constant of an electric circuit, the type of a tire and air pressure are eliminated by said coefficient correction and when braking is applied, the vehicle velocity can be measured continuously to match with actual state.

IPC: G03F7/11
Filed: 1998-09-08
Abstract: PROBLEM TO BE SOLVED: To form a pattern having excellent adhesion property of a chemically amplifying type resist on a silicon nitride film in a short time.

Title: Controller for rotational speed of inverter-type engine generator
Inventor: OGURA KAZUHIKO
IPC: F02D29/06
Filed: 1990-10-09
Abstract: PURPOSE:To shorten the low-voltage duration of generation output at the time of an abrupt increase in load, thus preventing a stall, by providing means for calculating a target speed and means for causing the engine speed to increase in response to an abrupt increase in load. CONSTITUTION:When output current becomes larger and output voltage V begins to decrease from rated voltage V0, a voltage comparing means 7b actuates a speed adjuster 9 to increase fuel supply. As a result, the rotational speed of an engine 1 rises. Therefore, the operating curve (n1-n10) shifts left to right, and simultaneously the rated voltage V0 is recovered. When the output current A becomes smaller and the output voltage V begins to rise from the rated voltage V0, the voltage comparing means 7b actuates the speed adjuster 9 to decrease the fuel supply. As a result, the rotational speed of the engine 1 lowers. Therefore, the operating curve shifts right to left, and the output voltage V is back to the rated voltage instantly.
